CARBURETER.

SPECIFICATON forming part of Letters Patent N o. 683,401, datedSeptember 24, 1901.

i Application iiled October 18, 1900. Serial No. 38,210. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM P. HoUZE, a citizen of the United States,residing at Paris, in the county of Henry and State of Tennessee, haveinvented certain new and useful Improvements in Carbureters; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in carbureters, and it isembodied in the novel parts, arrangements, and combinations of partshereinafter described, and particularly set forth in the claims.

. The object and purpose of the present invention is to provide anapparatus with means for insuring a uniform gas at any stage of theliquid hydrocarbon.

A further object of the invention is to provide a gas-producingapparatus with an airreceptacle and air-percentage valves for generatinga uniform gas at any stage of the liquid hydrocarbon.

A further object of the invention is the provision of a novelconstruction of carbureting-chamber whereby the maximum production ofgas is obtained.

A further object of the invention is the provision in thecarbureting-chamber of a series of dividing-walls to form air and gascurrents, the passages between the dividingwalls being provided withsuitable wicking to enable the more ready evaporation of the hydrocarbonand to furnish the maximum surface for the liquid.

A further object of the invention is to provide a novel and eiiicientmixer and equalizer for equalizing the quality of the gas produced.

A still further object of the invention is to construct a carbureter forgenerating illumihating-gas which will be simple in construc` trated anapparatus embodying the invention 5 but I desire it understood that I donot limit the invention in its useful applications to the particularconstruction which 4for the sake of an understanding of the invention istherein delineated.

In the drawings, Figure 1 is a perspective view of an apparatusembodying my invention... Fig. 2 is a vertical sectional view throughthe air-receptacle,carbureting-chamber,and combined mixer and equalizer.Fig. 3 is a horizontal sectional view through the air-receptacle,showing in plan the air-percentage valve. Fig. 4 is a'horizontalsectional view through thecarbureting-chamber; and Fig. 5 is ahorizontal sectional view through the upper portion of the mixer andequalizer, showing the air and gas pipes and mixing-partition in plan.-

Referring to the drawings, wherein like reference characters refer tosimilar parts throughout the several views, B indicates anair-receptacle provided with an air-inlet pipe A, through which air issupplied to the receptacle B under suitable pressure by any desired 0rconvenient means. (Not shown.)

D indicates a carburetingchamber the upper portion of which isconnected, as by means of a suitable pipe C, with the lower portion ofthe air-receptacle.

F represents a combined mixer and equalizer the upper portion of whichis also connected, as by means of api pe E, to the lower portion of theair-receptacle B. The carbu-` reting-chamber is `provided with afillingpipe, (indicated at G.)

. The carbureting-chamber D is divided by means of horizontal partitionsG' into a plurality of compartments, each communicating with the otherby means of a .vertical pipe H, which does not extend to the partitionor cover above and which is open at its upper end. q Each pipe Hisprovided at its top with a small recess or notch I to allow the liquidto pass from the one compartment to the one next below through the pipeH clear of the air and gas at the commencement of the operation oftheapparatus. :As will be seen, the pipe C leads to the upper compartment.A vertical pipe .I communicates with the lower portion of the Vlowercompartment and a simi- IOO tion of the intermediate compartment. In thepipe J is aY oat provided with avertical stem which is adapted to risewith the liquid in the compartment and indicate the amount therein. Itwill be understood that any desired number of horizontal .compartmentsmay be provided, in the present instance three being shown. The pipes G,J, and J are provided with suitable closures-as, for instance, caps gand j. The filling-tube G and the pipes J and J will allow the residuumto be pumped from the carbureting-cham-ber, and they also serve asvent-pipes in lling. Y p

L indicates Vertical partitions dividing the several compartments of thecarburetingchamber into passages communicating with each other by meansof restricted openings or ways M. 'By this construction 'I obtain a-greater pressure to the volume, owing to the confinement of the air inthe passages, and thereby the agitation of the hydrocarbon will beincreased, which will 'produce a greater quantity of gas. K indicates apiece of wicking which is placed` in the upper compartment opposite orbelow the air-inlet pipe O, and in each of the passages formed betweenthe vertical partitions L are oppositely-arranged 'inclinedwicking-baffles which extend at an angle to the partition in such manneras to cause the air to pass'in a zigzag direction through the passages.The Wickin g K and L by capillary attraction raise the liquid from thecompartments and distribute the same over an extended-surface in thepath of the air, thereby insuring a very perfect commingling of the airand vapors from thehydrocarbon and insuring a freer vaporization of thehydrocarbon. V'ithin the air-receptacle B is a valve-seat B', providedwith ports communicating with the `pipes C yand E to thecarbureting-chamber and mixer and equalizer, respectively. As shown,these ports are at diametrically opposite points of the seat. Rotatablymou nted above the seat B is my improved percentage-valve B2, which, aswill be seen, is provided with a series of ports arranged equidistantfrom the center of rotation of the valve and adapted to the registerwith the hereinafter described.

rthe air vessel, which is provided with indications, as shown in thedrawings, to indicate' the position of the valve B2.

The combined mixer and equalizer is, as before stated, connected to theair vessel by means of the pipe E. The latter'enters the casing of themixer and equalizer and terminates in a circular pipe P, providedWithperi forations, the combined area of which perfo- Vbined mixer andequalizer.

v ration is equal to the area of the largest port in the valve BZ,opening to themixer and equalizer.

N indicates a pipe leading from the upper portion of the lowermostcompartment of the carbureting-chamber to the upper portion of thecombined mixer and equalizer, where it is provided with a horizontalperforated pipe N', the combined area of the perforations of which isequal to the area of the inlet-pipe A for the air. Below the pipe N andthe pipe P' is a horizontal perforated partition Q, and

ufrom Vthe outer edges of this partition depends an inverted-cone-shapedimperfora-te partition Q', forming a funnel opening at the lower centralportion into the casing of the mixer and equalizer. Below the mouth ofthe funnel is a horizontal partition R, between which and a similarpartition spaced therefrom is coniined a coarse woolen cloth or thelike. The central portion of the partition R, below the exit from thefunnel, is imperforate,or the perforations are covered-as, for instance, by means of a plate R2.

S indicates the gas-supply pipe, which leads from the lower port-ion ofthe mixer and equal-A izer to the burners.

In operation the carbureting-chamber will be supplied with a liquidhydrocarbon, such as gasolene, through the iilling-tube Gr, the liquidpassing into the upper compartment, from which it overliows through theconveyerpipe H to the compartment below, which it fills to the height ofthe conveyer-pipe H therein, when it will overflow to the next lowercompartment, and so on to succeeding compartments,`if more than threeare employed. The air, as will be understood, is supplied under pressureto the air-receptacle A, from which it passes through the pipes C and Eto the carbureting-chamber and com- The percentage or proportion of airsupplied to the carbureting-chamber relative to that supplied to themixer and equalizer is controlled and relatively changed by means of thepercentagevalve B2 in the following manner: At the commencement of theoperation the indexpointer B4 will be set at the point l on the scale,which, through the operating-stem, will turn the valve so that the portO will register with the pipe E to the mixer and equalizer and the portO' will register'with the pipe C to the carbureting-chamber. The port Obeing koi' an area of, say, eighty per cent.

correspondingly large percentage of air to the mixer 'and equalizer, andthe gas produced will be a mixture composed of eight or nine parts, moreor less, of air and one or two parts'of vapor, which will make abrilliant smokeless flame. After the carbureter has been in use for sometime, when the gasolene becomes heavy and the same air will no longerabsorb the same amount of vapor, it is necessary to increase the supplyof air to the carbureting-chamber, and to do this the in- IOO IIO

'of the area of the port O' will deliver a y dex-pointer is moved to thepoint 2 on the scale, when the port O2 will open to the mixer andequalizer and the port O3 to the carbureting-chamber. The port O2 being,say, sixty per cent. of the area of the port O3, more air will be forcedto the carbureting-chamber in proportion to that supplied to the mixerand equalizer and gas of the same richness as before will be produced,thus insuring the same brilliant smokeless flame. The valve is thus fromtime to time, as it becomes necessary, moved to bring the ports O4 andO5 and O6 and O7, respectively, into communication with the combinedmixer and equalizer and the carbureting-chamber.

In the drawings the ports O and O', O2 and O3, &c., are shown asdiametrically opposite each other in the valve. This is not essential,it only being necessary to have the relative arrangement such that whenthe ports O O2, &c., register with the pipe to the mixer and equalizerthe ports O' O3, dac., shall open to the carbureting-chamber. It will beseen that the combined area of the ports opened to thecarbureting-chamber and the mixer and the equalizer is the same as thearea of the inlet-pipe A to the air-receptacle. When it is necessaryTafter a continued use of the apparatus to supply all of the air to thecarbureting-chamber, the valve is turned to bring the port O8 intoregistration with the pipe C. In this position of the valve the pipe Eis closed and no air passes to the mixer and equalizer.

The air and vapor which is very thoroughly mixed and com mingled in thecarburetingchamber by passing through the various passages and intocontact with the wicking, as before recited, passes to the` mixer andequalizer, into which it is discharged in small jets through theperforations in the pipe N and mixed with the 'air entering through theperforations in the pipe P. The mixture will be more thoroughly mixedand equalized by being forced by the pressure through the perforatedpartitions Q, after which it is contracted and concentrated by theconical partition Q' and then passed through the parti- Having thusdescribed my invention, what is claimed, and desired to be secured byLetters Patent, is

l. In a carbureter, the combination of a carburetin gchamber, a mixerand equalizer, an air-receptacle in the air-supply to thecarbureting-chamber communicating with the mixer and equalizer, andmeans :in the airreceptacles `for relatively increasing the supply ofair to the carbureting-chamber and decreasing the supply to the mixerand equalizer, substantially as described.
